Recent overhaul of the X server infrastructure lead to the appearance of Kernel
Mode Setting (KMS) and Graphics Execution Manager (GEM) to rejuvenate the X
world. This has a number of benefits, from improving 3D GPU support,
deprivileged X server to in-kernel video mode management, which can be very
helpful when it is necessary to debug a live system using ddb(4).

The goal of this project is to add the missing bits inside NetBSD, most notably
KMS and GEM. Testing the port using a recent driver like nouveau would be worth
the effort.
